It’s time for BlackBerry to pull the plug on its mobile OS

Last week, Facebook decided to drop support for BlackBerry’s mobile OS, which means its app will soon cease to work on the company’s devices. Once the app disappears from BlackBerry World, users will have to visit the social network’s site to access it.

It’s the latest in a series of developments pointing to the slow but eventual demise of BlackBerry’s platform. Last month, WhatsApp announced its plans to discontinue its BlackBerry 10 and BBOS apps by the end of the year. That’s two of the world’s most popular apps crossed off the company’s roster this year.
